Application filed my 27, 1915. serial No. 310,826.

Tool; whom it may concern.

the city and county of San Francisco and State of California, have inyented new and useful Improvements in 'Pipe Cleaning and Painting Machines, of which the following is a specification.

Another object of the invention is to provide means whereby power. from .the motor istran'smitted to operate the cleaning and painting devices employed as the machine travels; and also to provide means for adjusting the machine as a'whole to handle pipes of varying diameters.

Further objects will hereinafter appear.

The inventionconsists of the parts and the construction and combination jof parts as hereinafter more, claimed, having reference to the accompanying drawings, in which Figure 1 is a side elevation of the ma chine. Fig. 2 is a plan view of same. Fig.

3 is a front end view. Fig. 4 is a cross section on line 44.of Fig. 1. Fig. 5 is a cross section on line 5-5 of Fig. 1. Fig. 6 is a cross section'on line 6-6 of Fig. 1. Fig. 7 is a cross section on line 77 of Fig. 1. Fig. 8 is a cross section on line 8-8 of Fig. '1. Fig. 9 is a cross section on line 9-9 of Fig. 1. Fig. 10 is an'enlarged detail elevation of the rear end of the machine, partly in section.

A indicates the pipe line to be cleaned and painted. Adapted to be supported by wheels 2-and 3 on the pipe line and to travel along same as on a. trackis a carriage 4, in

which is mounted a motor '5 from which power istransmitted to drive or propel the carriage in the following manner: 6 indicates a main drive shaft directly connected with the motor by means of a clutch 7.

shaft. is a shaft 9 which is connected with the mainshaft by means of the worm gear drive, indicated at 10, and secured on said I Specification of Letters Patent.

Be it known that I, RUSSELL H.- 'a'cit zen of the United States, residing in fully described and rate'naea Mar.- 21, 1916.

shaft is a pair of sprocket wh' eels'll' from which power is transmitted, by chains 12,-

to'apairot sprocket wheels 13 secured on a. shaft 14 upon which the rear carriagesup- '--porting wheels 3 are also secured. ,The

flanges of the rear wheels 3 arepreferably.

tapered to fit the contour of the pipe and in this manner provide a traction face whichis suflicient to propel the carriage in a forward direction. Both the rear andforward supporting wheels of the, carriage are ad- .justablv mounted in bearing blocks, such as indicated at 15 and 16, for purposes hereinafter to be described.

Suspended from the rear end of the main frame 8 is a sub-frame 1'1 which is formed in two sections, one on each side of the -main frame, and secured in said frame and tegrally with, or otherwise secured, to each pinion-is a head member 25, in which is pivotally mounted,,as at 26, a pluralitv of arms 27, on the outer end of .each of which is journaled a conical-shaped roller 28.

Secured on the bearing ring 18 is a stationary internal spur gear 29, and engageable on one side with the internal gear 29 and on the other side with a pinion 24 is an intermediate pinion 30, one being pro vided for each pinion 24. The pinions 30 are secured and journaled'on the forward plate 31 which is secured to drum 21 upon which pinions 24 are also secured and journaled. "A-rotarv movement transmitted to drum 21, through pinion 23- and spur gear 22. will cause the pinions 24 to revolve at a high speed, asmovement is transmitted to same through the stationary internal spur gear 29 and intermediate pinions 30. The high revolving speed transmitted to the pinions 24 while the main drum 21 is revolving at a comparatively slow speed will causethe pivoted arms 27 to swing out by centrifugal action, thus producing a ham mer-like acti non the pipe which not only removes and loosens any scale or that forumtion on the surface of the'pipebut also any other foreign matter whieh might be present v j V V Mounted interiorly of the revolving drum 21 is a plurality of radially disposed steel brushes 32', the inner: ends of which contact with the face of the pipe. Each brushis held against the pipe by a spring 32 interposed between the headof the brush and an adjustable bearing plate 33. The brushes are otherwise held inposition by gulde rods 34 projecting through openmgs formed in the drum 21. Practically any degree of pressure may be brought to bear on the thoroughly cleaned before the paint is applied, as will hereinafter be described.

Secured and jdurnaled on a plate 35 secured on the rear end of the drum is a plurality of pinions 36, and secured to the hub of each pinion 36 is a plurality of outwardly extending arms 37 "of varying lengths, andsuitably secured on the outer end of each of said arms is a paint brush-38. The pinions 36 are all so positioned. as to intermesh with .a stationary internal sprocket gear 39 which .is secured to and carried by the bearing ring 19. Movement is in thisimanner transmitted from the revolving drum '21 to revolve the pinions 36,

with connected brushes 38, at a suitable speed.

Secured to bearing ring 19, exteriorly of plate 35 and the internal sprocket gear 39,

:is an annular trough-shaped pan 40, and supplying said trough with paint, from a tank 41, is a pipe 42 which is branched, as at 43 and 44, to admit paint on each side of the trough. The paint admitted to-the trough is picked up by the revolving brushes as these are carried around by the main revolving drum 21 and is in turn supplied to the face of the pipe, as the outer ends of the brushes are intermittently contacting with the pipe at one time and with the inner face of the trough at another time; the

' offset position or the varying lengths of the arms 37. permitting a considerable surface to be covered at one time.

Secured on the outer end of each stud 44, upon which the pinions 36 are journaled, is

' an extension arm 45, and pivotally mounted on the outer end of each of said arms is a brush supporting arm 46 imwhich is suitably secured a smoothing brush 47, one being provided for each arm. These brushes position with relation to the revolving in-unison with the drum 21 are provided for the purpose of smoothing out the paint applied by the brushes 38. Mounted interiorly of the rearmost bearing rin 20 is'a revolving ring 48 which is driven rom the main shaft by means of the sprocket driveindicated at 49. Secured to 1 this sprocket is a plurality of outwardly extending arms 50, and carried on the outer end of each arm and engageable with the face.

of the pipe is a finishing bru'sh 51; the provision of the third or last set of brushes permitting the paint previously applied to be thoroughly smoothed and finished.

From the foregoing description it will be seen that the pipe is first thoroughly hammered, brushed or cleaned. The'paint is then applied by the brushes 38, then smoothed out by the brushes 47 and finallyto be connected by coil springs, such as in-' dicated at 53. This not only causes the several smoothing brushes to engage the pipe with equal pressure but also permits the arms to move in and out with relation to the surface of the pipe and permits pipes of varying diameters to be handled; the

adjustable mounting of the brushes 31 being provided with the same object in view.

By referring to Fig. 5, it will be seen that the face plate 31 is provided with two stud support openings, such asindicated at 61 and 62. The studs upon which the pinions 24 are journaled may in thismanner be moved radially inwardly or outwardly with relation to the center of the drum, permitting the pivoted hammers or rollers to be moved in or out intothe most efiicient diameter of the pipe handled.

By referring to Fig. 1, it will be seen that the paint tank is provided with an interior coil 63, one end of which is connected with. the discharge outlet of the water circulating jacket on the edge 5. The heated water from the engine, before returning to the main cooling tank 64, is passed through the coil in the paint tank, causing the temperature of the paint to be raised-to the desired temperature; the vol ume of paint admitted to the trough being The coat of paint is in this controlled by a valve 65. A second valve 66 which may be termed the automatic cut ofi valve is also provided. This is connected by a link67 With the main engine clutch lever 68 so that, when the clutch is thrown out to. stop the carriage, the paint thereby reducing friction to a minimuniand a to the pipe.

supplied through pipe 42 to the'trough will be automatically cut oif and prevents the paint from entering the trough and overflowing when the carriage and paint applying brushes are standing still.

The adjustable mounting of the main bearings 15 and 16 is provided for the purpose of maintaining the carriage at a fixed position with relation to the center of the pipe handled, thus maintaining the main. revolving drum 21 and supporting bearing rings in a concentric position withrelation' Ball races, such as indicated r at 70, are preferably interposed between the main bearing rings and the several revolving parts, such as the drum 21 and -ring4 8,

permitting a free movement of'the revolving parts.

The materials and finish of the several parts of the machine are otherwise such as the experience and judgment of the manufacturer may dictate. v
